Tracking and reporting status of automated clearing house ("ACH") transactions. An ACH operator receives an ACH file comprising an ACH batch comprising an ACH transaction item for ACH processing. The operator tracks a status of the ACH file, batch, and item during multiple ACH processing events. A customer communicates a query for the status of the ACH file, batch, or item. The operator retrieves the tracked status of the ACH file, batch, or item and presents the tracked status to the customer. The ACH processing events typically comprise receiving the ACH file, confirming the ACH file, approving the ACH file, processing the ACH file, processing the ACH batch in the ACH file, and processing the ACH transaction item in the ACH batch. The operator can present a graphical depiction of errors the ACH file header, batch header, or item record detail.
